@nikitabobko I would like to try my hand at this "good-first-issue".

[jeffwindsor]

Looking over the background information in

• https://nikitabobko.github.io/AeroSpace/guide#tree
• https://i3wm.org/docs/userguide.html#_swapping_containers
• video in issue [Feature Request] Swap window position keyboard shortcut #61
• https://github.com/nikitabobko/AeroSpace/blob/main/Sources/AppBundle/tree/TreeNodeCases.swift#L12

I became confused between the terminology and intent of this feature. Is the intent that the swap is applied to Leaf Nodes (Windows) or Non-Leaf Nodes (Containers, excluding workspaces)?

@jeffwindsor Leaf nodes (windows). It should work similar to move command.

@jeffwindsor Also please reuse swapWindows for mouse https://github.com/nikitabobko/AeroSpace/blob/main/Sources/AppBundle/mouse/moveWithMouse.swift#L59

[jeffwindsor]

Excellent. Do you have a structural preference for reuse? as in should the swapWindows function be moved to a shared location as part of this second use?

[jeffwindsor]

I noticed the .swiftpm directory was not excluded in the .gitiginore. Is it ok to add that to the project .gitignore?
If not, no problem, I will add it else where on my machine.

@nikitabobko I forgot to tag you on the above questions.

These are insignificant questions, proceed as you think is best
